Universe Probably Not a Hologram After All

An astrophysicist’s attempt to measure quantum “fuzziness” — to find out if we’re living in a hologram — has been headed off at the pass by results suggesting that we’re probably not.

In October 2010, Wired.com reported on Craig Hogan’s experiments with two of the world’s most precise clocks, which he was using to try and confirm the existence of Planck units — the smallest possible chunks of space, time, mass and other properties of the universe.

Hogan’s interpretation of results from the GEO600 gravitational wave experiment had shown a quantum fuzziness — a sort of pixelation — at incredibly small scales, suggesting that what was perceive as the universe might be projected from a two-dimensional shell at its edge.

However, a European satellite that should be able to measure these small scales hasn’t found any quantum fuzziness at all, contradicting the interpretation of the GEO600 results and indicating that the pixelation of spacetime, if it exists, is considerably smaller than predicted.

Intel developing ‘physical holograms’

Intel is researching dynamic physical rendering, using silicon to create three dimensional objects that can be touched and changed.

The application is still very sci-fi, but the idea behind the project is that it will create what could be described as a touchable, malleable hologram.
